    It only serves a basic user, without major needs.

    In the course of the updates it has been losing performance in several aspects.

    I love the device, Windows 10 Mobile no

    This mobile factory has a very fast camera, it is very fluid and eaten to use, with Windows Phone 8.1 The problem is Windows 10 Mobile. Adds a host of useful options present in high-end phones, but this is a device with mid-range specifications and it shows. In addition the system has recently been released and is not a priority for developers to update their apps, so now they are not very fast or very stable, which significantly compromises the user experience. The best, Cortana and the camera. The worst, stability.

    Positives
    • Cortana
    • Camera
    • Resistance
    • dark mode
    Negatives
    • little stability
    • Battery something just after one year

What is a Ki score?
Ki is an automatic score based on the specifications and prices of devices. It is calculated using over 200 variables to rank smartphones, tablets and other devices from best to worst.
How do we calculate the Ki?

In this case, to determine the score we evaluate 5 general aspects:

  • Design and screen
  • Hardware and performance
  • Camera
  • Connectivity
  • Battery

Once these 5 factors have been rated, we introduce the price variable. This means that any two devices with the same ratings get a different Ki score for quality vs price.

Even a device objectively worse than another may have a higher Ki score if it has a better price.

Does the Ki score change?

The Ki varies as time goes by. As new devices with better specifications enter the market the Ki score of older devices will go down, always being compensated of their decrease in price.
